(Supuestos) Sondeos internos de Chicago

National Journal:

Internal Obama polling data show that all swing states have tightened up and that Romney is within the margin of error in Colorado, Florida, and Virginia. In Ohio, the gap has closed from what was an 8 to 10 point Obama lead to just outside the margin of error. It's now a dogfight across the swing-state battlefield and any sense of pre-debate complacency that some Obama hands feared was creeping into both turnout and fundraising has vanished.

Como ya dije el otro día, los sondeos internos de los candidatos hay que recibirlos con suspicacia.
